MAGNETIC PERFORMANCE «E» TYPE CORES
All the cores of standard series have a control about the total losses in the iron and the magnetizing current at an induction max B = 1,7 Wb/m² and a frequency 50 Hz as follow:
– Total losses less than 2,7 w/Kg.
– Magnetizing power VA/Kg. less than:
A = Net sectionaf each leg in Cm2
W = Net weight of the core in Kg MAGNETIC PERFORMANCE «E» TYPE CORES
All the cores of standard series have a control about the total losses in the iron and the magnetizing current at an induction max B = 1,2 Wb/m² and a frequency 400 Hz as follow:
– Total losses less than 2,7 w/Kg.
– Magnetizing power VA/Kg. less than:
A = Net sectionaf each leg in Cm2
